Patent number: 5334272Abstract: An easily openable container comprises (a) a multilayer container body which includes an innermost layer and an adjacent layer contacting the innermost layer, a recessed portion and a flange and (b) a lid member melt sealed to the innermost layer of the multilayer container body at the flange, where the innermost layer and the adjacent layer are peelable from each other and having between them a peel strength smaller than the peel strength between the lid member and the innermost layer. The flange has two circular notches made in the innermost layer, and the multilayer container body and the lid member are melt sealed between the two circular notches, with the proviso that a portion of the melt sealed area projects outwardly from the outer circular notch, and a depression is made in the innermost layer at the outermost edge of the projecting portion of the melt sealed area by pressing the innermost layer through the lid member.Type: GrantFiled: July 21, 1992Date of Patent: August 2, 1994Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Yukio Takata, Takeshi Shinohara

Patent number: 5141126Abstract: A container, a method of an an apparatus for forming cuts in the container are disclosed. Weakening lines serving as cutting lines are formed on inside of the sealing portion and outside of the flange portion of the container, and a non-sealing region is formed at the position at which a part of the outer weakening line is included. These weakening lines can be formed by rotating the container and bringing the notching blades into contact with the flange portion.Type: GrantFiled: June 30, 1989Date of Patent: August 25, 1992Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Yukio Takata, Takeshi Shinohara
